Room acoustics can be a bear to deal with, especially so when the room has to serve other family uses, or, for example, meet the decorating needs of a spouse. That said, small changes in speaker position and adjusting things like toe-in can often have a dramatic effect even if you can't add much in the way of wall treatments or the like.
Tube amp bias adjustment advice
I biased my first set of tubes on my 211 amp recently and am hearing more volume from the left channel. Does that mean I need to turn up the bias on the left channel to center the soundstage? Thank you in advance.
